Question

我在根目录中有一个CMakeLists.txt的项目，其中包含test/子目录中使用add_subdirectory并带有标记EXCLUDE_FROM_ALL的项目。测试需要父项目的所有include目录。最优雅的方法是什么？

Answer 1

如果您正在使用include_directories()添加目录，则这些目标应向下传播到test subdir中的目标。请注意，相对路径是相对于当前源dir：

include_directories：向构建添加包含目录。 include_directories（[AFTER | BEFORE] [SYSTEM] dir1 dir2 ...）将给定目录添加到编译器用于搜索包含文件的目录。相对路径被解释为相对于当前源目录。

您将主目录和子目录测试保存在完全独立的项目中。我想你是通过单独调用cmake并再次进行构建测试。毫不奇怪，您的主项目include_directories对测试项目没有影响。

你提到命令add_subdirectory，（应该用来包括你的主目录中的test）但你实际上并没有使用它......

添加的最佳方法是将根项目的目录添加到CMake中的子目录中
